Drinking Oil - Piston ring replacement in 14k mls A3 1.8T
I have an A3 1.8TFSI Sportback (09 plate) which I bought back in December (at about 13K mls) from Audi Approved Used - It had a slight door rattle so I took it back to the dealer who sold it to me in early Feb.
They claimed it was almost out of oil (after being full when I first bought the car), and topped up with 4L of oil - I asked if this was normal (only about 1.2k mls on) and they assured me it was.
Wind forward to now, its eaten all the oil again. Taken the car into another dealer who tells me the piston rings need replacing. I didn't have time to talk to them properly, and can't get through to them now - is this a common problem, and if not, are they fixing the symptom as opposed to the cause? Will they rebuild the engine to the same standard as it was from factory, or should I be going back to the original dealer and reading the riot act? I understand that if its been low enough on oil in the past to cause such damage to the piston rings etc, there could be damage to bearings etc too - I don't wan't to end up with an engine that packs up 50k mls down the line out of warranty because of damage done now.
Any advice would me most appreciated!
